The announcement this week that scientists may or may not have discovered a new subatomic particle has riled up the physics world. So how do we know for sure whether the particle is real or not? A ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

Richard Feynmann noted more than once that complementarity is the central mystery that lies at the heart of quantum theory. Complementarity rules the world of the very small… the quantum world, and ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

Scientists used the Compact Muon Solenoid (CMS) data to reveal, for the first time, a universal feature within jets of subatomic particles, which are produced when high-energy protons collide. Their ...

Rosemary Fowler (née Brown) discovered a type of subatomic particle, the kaon—but left the university before earning her doctorate. Rosemary Fowler (seated) receives her doctorate from Sir Paul Nurse, ...
